How ChangeNOW Became the Most-Used Swap Route Inside Zelcore’s Multi-Chain Wallet

By 2021, Zelcore was more than just a basic crypto wallet. It let users manage assets across over 70 blockchains, giving them multi-chain access while keeping control of their private keys. This wide asset support was a big advantage, but it also revealed a new challenge. Users could store and manage assets in the wallet, but they still relied on outside exchanges for liquidity. For a multi-chain, non-custodial wallet, this was a real issue. Simply storing assets was no longer enoughliquidity had become a key part of what users expected. Why External Swaps Did Not Fit The Product The problem showed up when users wanted to take action. Someone could open Zelcore, manage assets on different chains, and decide to swap one asset for another, but then had to leave the wallet to finish the transaction elsewhere. This break happened right when users were most engaged. For Zelcore, the issue was more than just a clunky interface. The wallet focused on self-custody and protecting user data. Using outside exchanges meant dealing with things like custodial steps, identity checks, third-party controls, and a transaction process that didnt match the wallets approach. Why Building Liquidity In-House Was Not The Answer Zelcore also had to choose what problems to take on. Building an exchange layer was much more than just adding a swap button. It would have required handling routing, finding liquidity, managing providers, dealing with KYC and AML rules, sorting out licenses, and following different local regulations. For a wallet team, this wasnt just another featureit was a whole new business. The product also needed to support many assets right away. If the swap feature was limited, it would hurt Zelcores reputation as a strong multi-chain wallet. And if the exchange experience was poor, users would lose trust even faster than if there was no swap feature at all. Zelcore needed to offer exchange access without turning into an exchange itself. Bringing Swaps Into Zelcore With Changenow In 2021, Zelcore added the ChangeNOW Exchange API, so users could swap assets right inside the wallet. This let people move between assets without leaving the app, and Zelcore didnt have to run its own liquidity service or change how it handled custody. Swaps became a built-in part of the wallet experience and a broader DeFi surface. With that much product change, a single launch-period uplift would not say much about the partnerships real value. The clearer test was whether the integration continued to work as Zelcores architecture changed. When Zelcore switched from working directly with providers to using an aggregated exchange backend, it set a higher standard. ChangeNOW now had to compete with many CeFi and DeFi options. In an aggregator, providers are judged by how well they perform under pressure. They compete on things users and teams notice right away, like rates, speed, settlement quality, route availability, and support. If a provider falls behind, the aggregator makes that clear right away. What the partnership changed for Zelcore The integration changed the role of swaps in the product for good. Now, users could exchange assets inside the wallet, which supported more activity and created a new revenue stream based on real wallet use. For listed assets and blockchain projects, the wallet offered more than just visibilityit gave them a direct way to be used. Meanwhile, the engineering team could keep focusing on chain support, custody, backend aggregation, and core wallet features. Conclusion: Flow Follows Execution For wallets, dApps, and multi-chain products, the lesson is clear: letting users hold assets is only the beginning of the experience. Closing the liquidity gap with embedded infrastructure transforms a storage tool into a seamless transaction hub. Zelcore teas summarizes the outcome directly: Five years after the original integration, ChangeNOW is the most-used swap provider in Zelcores aggregated exchange backend, outperforming every other route we offer, CeFi and DeFi alike. The partnership held through a full crypto market cycle and Zelcores transition to backend aggregation, a transition that displaces many providers, but that ChangeNOW navigated alongside us. In an aggregator, flow follows execution, and across rates, speed, settlement, and support, ChangeNOW is the route our users keep coming back to.
